Abstract

La présente invention se rapporte à un corps de masque respiratoire qui définit une zone d'air respirable pour un utilisateur et qui comporte une soupape d'arrêt. Selon un mode de réalisation donné à titre d'exemple, le corps de masque comprend un ou plusieurs orifices d'entrée configurés pour recevoir un ou plusieurs éléments de source d'air respiratoire. La soupape d'arrêt est utilisable entre une position fermée et une position ouverte et lorsqu'elle se trouve en position fermée, la soupape d'arrêt empêche une communication fluidique entre le ou les orifices d'entrée et la zone d'air respirable et la soupape d'arrêt retourne à une position ouverte en l'absence d'une force appliquée.
